[0001] The present invention relates to a food nutrition assessment system and method, and more specifically, to a food nutrition assessment system and method for balanced food intake.

[0002] In order to lead a healthy daily life, it is very important to provide our body with the necessary nutrients through a balanced diet.

[0003] People consume individual foods in isolation, but they also consume them in the form of dishes prepared with various ingredients. Since a single food contains a variety of nutrients, nutritional assessments to determine whether an individual is receiving adequate nutritional intake must include data that reflects the nutritional complexity of the food.

[0004] Traditional nutritional assessment systems typically compare nutrient intakes to Korean nutrient intake reference values, providing information on nutrient deficiencies or excesses. While this is straightforward from a nutritional perspective, it lacks practical application in providing users with solutions to their nutritional intake issues, making it difficult to improve nutritional intake behavior.

[0005] There is a need for a system that provides users with direct, real-life information that can be easily applied to improve their eating habits by understanding information about their nutritional intake levels based on their meal records.

[0006] In other words, there is an urgent need to develop and utilize a nutritional intake solution model suitable for the diverse food ingredients consumed by Koreans.

[0077] Figure 9 is a flowchart of a food nutrition assessment method for balanced food intake according to one embodiment of the present invention.

[0078] Referring to FIG. 9, a user terminal (200) receives food intake from a user and uploads it to a food nutrition judgment server (300) (S101).

[0079] At this time, the user terminal (200) may be configured to receive the user's voice through the microphone module (201) and recognize the voice input from the microphone module (201) through the voice recognition module (202). In addition, the user terminal (200) may be configured to confirm and upload the user's food intake through the voice recognized by the voice recognition module (202) through the food intake confirmation module (205).

[0080] Next, the food nutrition judgment server (300) judges the user's food nutritional status based on the food consumed uploaded from the user terminal (200) (S102).

[0081] Here, if the food to be consumed is a food of a single ingredient, the main ingredient is set, and if the food to be consumed is not a food of a single ingredient, the food recipe of the food to be consumed is searched in the food recipe database (101), and the food / food group mapping information stored in the food / food group mapping information database (102) is referenced to classify the food group according to the main ingredient or the searched recipe.

[0087] Figure 10 shows a more specific process compared to Figure 9.

[0088] Referring to Figure 10, when starting to record a meal through the application, the consumed items are input (S201).

[0089] Here, it is determined whether the input item is a single food item (S202).

[0090] As a result of the judgment, if the item is a single food, the food is classified into the corresponding food group (S203). If it is not a single food, the main ingredient food is found in the food recipe database (101), and the food / food group mapping information database (102) is referenced to classify the main ingredient food into the corresponding food group (S203).

[0091] Then, the cumulative total intake frequency of each layer of the food pyramid to which the food group belongs is calculated (S205).

[0092] Then, the relative ranking of each layer of the food pyramid is calculated (S206).

[0093] And, by referring to the food balance type database (103), a food balance type is assigned to the relative ranking combination (S207).

[0094] And the number of foods and food balance types by floor are visualized (S208), messages by food balance type are sent to the user terminal (200) (S209), and the foods consumed by food group are also displayed (S210).

[0095] FIG. 11 is a flowchart of a food balance typification process according to an embodiment of the present invention, and FIGS. 12 to 13 are drawings for explaining a food balance typification process according to an embodiment of the present invention.

[0096] Referring to Fig. 11, first, the food nutrition judgment server (300) uses a food (i row) X nutrient (j column) DB (S301). Fig. 12 illustrates an example DB regarding food nutritional components.

[0097] Next, the food nutrition assessment server (300) performs dimension reduction analysis (S302). At this time, the dimension can be reduced from j to two dimensions, and in the embodiment of the present invention, dimension reduction can be performed using the canonical correlation analysis (CCA) technique.

[0098] Next, the food nutrition assessment server (300) performs hierarchical clustering (S303). Here, i foods can be grouped into k food groups (S303). That is, in the embodiment of the present invention, food groups can be grouped through a hierarchical clustering process.

[0099] Next, the food nutrition judgment server (300) checks the cluster contribution nutrients for each food group (k) (S304).

[0100] Next, the food nutrition assessment server (300) compares and verifies the food group k results with the used DB values ​​(S305). Here, the number of food groups k can be reduced to one. Figure 13 schematically illustrates the previously verified food groups and cluster contributing nutrients.

[0101] Next, the food nutrition assessment server (300) classifies food groups (1) into four categories based on recommended intake frequency to construct a food group pyramid (S306). Figure 14 illustrates the structure of a four-tiered food group pyramid.

[0102] Next, the food nutrition assessment server (300) categorizes the user's food intake balance based on the shape of the pyramid formed based on the user's intake frequency at each pyramid level (S307). At this time, the food intake can be categorized into m types. Various types, such as diamond shapes, inverted triangle shapes, double triangle shapes, and square shapes, rather than circular pyramid shapes, are exemplified in Figure 15.

[0103] Although the present invention has been described with reference to the above embodiments, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
